The mother-of-two has picked this unusual spot to take her Christmas snaps in a big to raise awareness of the lack of changing facilities in disabled toilets.

Releasing a series of selfies leading up to 24th December, Sarah hopes to highlight the plight of people like her son Hadley, seven, who needs changing facilities in disabled toilets so he can go to toilet with dignity.

Sarah, who is mother to twins Erica and Hadley, who is a wheelchair user with cerebral palsy, has found that she has to resort to changing her seven-year-old son on the toilet floor because of the lack of changing facilities.

‘The slight embarrassment I feel from sharing these photos, is nothing compared to the indignity my son feels having to lie down amongst other people’s urine,’ said Sarah to Metro.

Whilst you're glugging free booze & having a good old knees up at your Christmas do, spare a thought for those who can't attend theirs because there is no toilet at the venue they can use. All public venues need #ChangingPlacespic.twitter.com/xRhqbNTV8Y
